General Description
The HMC590 is a high dynamic range GaAs PHEMT
MMIC 1 Watt Power Ampli er which operates from 6
to 10 GHz. This ampli er die provides 24 dB of gain,
+31.5 dBm of saturated power at 25% PAE from a +7.0V
supply. The RF I/Os are DC blocked and matched to 50
Ohms for ease of integration into Multi-Chip-Modules
(MCMs). All data is taken with the chip in a 50 ohm test
xture connected via 0.025mm (1 mil) diameter wire
bonds of length 0.31mm (12 mils). For applications
which require optimum OIP3, Idd should be set for 520
mA, to yield +41 dBm OIP3. For applications which
require optimum output P1dB, Idd should be set for
820 mA, to yield up to +32 dBm Output P1dB.

GaAs PHEMT MMIC 1 WATT
POWER AMPLIFIER, 6.0 - 10.0 GHz
Mounting & Bonding Techniques for Millimeterwave GaAs MMICs
The die should be attached directly to the ground plane eutectically or with
conductive epoxy (see HMC general Handling, Mounting, Bonding Note).
50 Ohm Microstrip transmission lines on 0.127mm (5 mil) thick alumina
thin lm substrates are recommended for bringing RF to and from the chip
(Figure 1). If 0.254mm (10 mil) thick alumina thin lm substrates must be
used, the die should be raised 0.150mm (6 mils) so that the surface of
the die is coplanar with the surface of the substrate. One way to accomplish this is to attach the 0.102mm (4 mil) thick die to a 0.150mm (6 mil)
thick molybdenum heat spreader (moly-tab) which is then attached to the
ground plane (Figure 2).
Microstrip substrates should be located as close to the die as possible in
order to minimize bond wire length. Typical die-to-substrate spacing is
0.076mm to 0.152 mm (3 to 6 mils).
Handling Precautions
Follow these precautions to avoid permanent damage.
Storage: All bare die are placed in either Waf e or Gel based ESD protective containers, and then sealed in an ESD protective bag for shipment.
Once the sealed ESD protective bag has been opened, all die should be
stored in a dry nitrogen environment.
Cleanliness: Handle the chips in a clean environment. DO NOT attempt
to clean the chip using liquid cleaning systems.
Static Sensitivity: Follow ESD precautions to protect against > ± 250V
ESD strikes.
Transients: Suppress instrument and bias supply transients while bias is
applied. Use shielded signal and bias cables to minimize inductive pickup.
General Handling: Handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. The
surface of the chip has fragile air bridges and should not be touched with vacuum collet, tweezers, or ngers.
Mounting
The chip is back-metallized and can be die mounted with AuSn eutectic preforms or with electrically conductive epoxy.
The mounting surface should be clean and at.
Eutectic Die Attach: A 80/20 gold tin preform is recommended with a work surface temperature of 255 deg. C and a
tool temperature of 265 deg. C. When hot 90/10 nitrogen/hydrogen gas is applied, tool tip temperature should be 290
deg. C. DO NOT expose the chip to a temperature greater than 320 deg. C for more than 20 seconds. No more than
3 seconds of scrubbing should be required for attachment.
Epoxy Die Attach: Apply a minimum amount of epoxy to the mounting surface so that a thin epoxy llet is observed
around the perimeter of the chip once it is placed into position. Cure epoxy per the manufacturer’s schedule.
Wire Bonding
Ball or wedge bond with 0.025mm (1 mil) diameter pure gold wire. Thermosonic wirebonding with a nominal stage
temperature of 150 deg. C and a ball bonding force of 40 to 50 grams or wedge bonding force of 18 to 22 grams is
recommended. Use the minimum level of ultrasonic energy to achieve reliable wirebonds. Wirebonds should be
started on the chip and terminated on the package or substrate. All bonds should be as short as possible <0.31mm
(12 mils).
